DRIVING AND OPERATING 213
.Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer and
vehicle control can be affected when
traction is reduced by water, snow,
ice, gravel, or other material on the
road. Learn to recognize warning
clues—such as enough water, ice,
or packed snow on the road to
make a mirrored surface —and
slow down when you have any
doubt.
.Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting
to a lower gear. Any sudden changes
could cause the tires to slide.
Remember: Antilock brakes help avoid
only the braking skid.
Track Events and
Competitive Driving
(V-Series Only)
{Danger
High-performance features are
intended for use only on closed
tracks by experienced and qualified
drivers and should not be used on
public roads. High-speed driving,
aggressive cornering, hard braking,
and other high-performance driving
can be dangerous. Improper driver
inputs for the conditions may result
in loss of control of the vehicle,
which could injure or kill you or
others. Always drive safely.
Track events and competitive driving
may affect the vehicle warranty. See
the warranty manual before using the
vehicle for competitive driving.
{Warning
Prior to each track event and again
before returning to public roads,
tighten the wheel nuts with a
torque wrench to the proper torque
specification. Wheel nuts that are
improperly or incorrectly tightened
can cause the wheels to become
loose or come off, resulting in a
crash. See Capacities and
Specifications 0397 for wheel nut
torque specifications.
Caution
If the vehicle is used for track
events and competitive driving, the
engine may use more oil than it
would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil 0316.
Axle Fluid
Axles must have 2400 km (1500 mi)
before being used in track driving.
Page 215 of 435
Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-14584312) -
2021 - CRC - 11/23/20
214 DRIVING AND OPERATING
The front, if equipped with AWD, and
rear axle fluid temperatures may be
higher than when driving in severe
conditions. Drain and refill with new
fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. SeeRecommended
Fluids and Lubricants 0392.
Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused to
the axle and would not be covered
by the vehicle warranty. Do not
drive as long or as fast the first
time the vehicle is driven on the
track or raced.
Engine Oil
Check the oil level often during track
events and competitive driving and
keep the oil level at or near the
upper mark.
Fuel
Use premium unleaded gasoline with
a posted octane rating of 93 at a track
event. Unleaded gasoline with a
posted octane rating of 91 may be
used, but performance will be
degraded. See Prohibited Fuels 0298.
Automatic Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at your
dealer.
Brakes
Brake cooling can be improved if the
front brake disc splash shield and
front tire deflector are removed.
Removing the shield will require that
the suspension bushings and wheel
speed sensor wires visible to the brake
disc be protected with insulated
thermal wrapping.
Caution
Removing the splash shield can
degrade wet braking performance,
as well as introduce brake pedal
pulsation, due to brake disc
exposure to road debris. Only
remove the front brake disc splash
shield and front tire deflector when
driving in track events.
Brake Pad Wear Sensors
(V-Series Only)
If equipped, the brake pad wear
sensors need to be removed from the
brake calipers prior to any track or
racing event. The original sensors can
be reinstalled if significant brake pad
wear is not observed. The sensor
should not extend beyond the brake
pad surface at the rotor contact.
If this condition is observed, the brake
pad life system needs to be disabled
until a new set of brake pads and
sensors are installed and the system
reset.

2021 - CRC - 11/23/20
DRIVING AND OPERATING 215
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a dry
boiling point greater than 279 °C
(534 °F). After conversion to the high
performance brake fluid, follow the
brake fluid service recommendations
outlined by the fluid manufacturer. Do
not use silicone or DOT-5 brake fluids.
Check the fluid level before each
competitive driving event.
Brake Fade Warning Assist
The Brake Fade Warning Assist
system monitors the performance of
the brake system. If the system
detects brake fade, or if the brake
fluid is near the boiling point, the
driver will be alerted.
Stage 1 :The Driver Information
Center (DIC) displays a “Reduce
Braking to Avoid Overheating”
message and brake pedal effort and
travel is increased. When the message
displays, the driver should decrease
brake pedal pressure. Stage 2 :
The Driver Information
Center (DIC) displays a “Brakes
Overheated Service Now ”message that
the brake fluid temperature is
excessive and is about to boil. The
system increases brake pedal effort
and travel, and will also limit vehicle
speed. The driver should immediately
start a cool down lap if on the track.
If this message displays, take the
vehicle to be serviced at your dealer.
Brake Burnishing
To prepare the brake system for track
events and racing, complete the
appropriate high performance brake
burnishing procedure described below.
New brake pads must be burnished
before racing or other competitive
driving.
Caution
These procedures are specific to the
V-Series with performance brake
linings package. This procedure
should not be run on other models
as damage may result.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnishing
procedure or damage may occur to
the powertrain/engine. See New
Vehicle Break-In 0223.
When performed as instructed, this
procedure will not damage the brakes.
During the burnishing procedure, the
brake pads will smoke and produce an
odor. The braking force and pedal
travel may increase. After the
procedure is complete, the brake pads
may appear white at the rotor contact.
Run this procedure in a safe manner
and in compliance with all local and
state ordinances/laws regarding motor
vehicle operation. Run this procedure
only on dry pavement.

298 DRIVING AND OPERATING
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by
volume.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
.For vehicles that are not
FlexFuel, fuel labeled greater
than 15% ethanol by volume,
such as mid-level ethanol blends
(16–50% ethanol), E85,
or FlexFuel.
.Fuel with any amount of
methanol, methylal, ferrocene,
and aniline. These fuels can
corrode metal fuel system parts
or damage plastic and rubber
parts.(Continued)
Caution (Continued)
.Fuel containing metals such as
methylcyclopentadienyl
manganese tricarbonyl (MMT),
which can damage the emissions
control system and spark plugs.
.Fuel with a posted octane rating
of less than the recommended
fuel. Using this fuel will lower
fuel economy and performance,
and may decrease the life of the
emissions catalyst.
Fuels in Foreign Countries
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock index
(AKI). For fuel not to use in a foreign
country, seeProhibited Fuels 0298.
Fuel Additives
TOP TIER Detergent Gasoline is highly
recommended for use with your
vehicle. If your country does not have
TOP TIER Detergent Gasoline, add
ACDelco Fuel System Treatment Plus
−Gasoline to the vehicle’s gasoline fuel
tank at every oil change or 15 000 km
(9,000 mi), whichever occurs first. TOP TIER Detergent Gasoline and ACDelco
Fuel System Treatment Plus−Gasoline
will help keep your vehicle’s engine
fuel deposit free and performing
optimally.
Filling the Tank
An arrow on the fuel gauge indicates
which side of the vehicle the fuel door
is on. See
Fuel Gauge 0100.
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
Follow these guidelines to help
avoid injuries to you and others:
.Read and follow all the
instructions on the fuel pump
island.
.Turn off the engine when
refueling.
.Keep sparks, flames, and

DRIVING AND OPERATING 303
necessary to go much farther beyond
the passed vehicle before returning to
the lane. Pass on level roadways.
Avoid passing on hills if possible.
Backing Up
Hold the bottom of the steering wheel
with one hand. To move the trailer to
the left, move that hand to the left. To
move the trailer to the right, move
that hand to the right. Always back up
slowly and, if possible, have someone
guide you.
Making TurnsCaution
Turn more slowly and make wider
arcs when towing a trailer to
prevent damage to your vehicle.
Making very sharp turns could
cause the trailer to contact the
vehicle.
Make wider turns than normal when
towing, so trailer will not go over soft
shoulders, over curbs, or strike road
signs, trees, or other objects. Always
signal turns well in advance. Do not
steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower gear
before starting down a long or steep
downhill grade. If the transmission is
not shifted down, the brakes may
overheat and result in reduced braking
efficiency.
Vehicles can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle could show
signs similar to engine overheating. To
avoid this, let the engine run,
preferably on level ground, with the
transmission in P (Park) for a few
minutes before turning the engine off.
If the overheat warning comes on, see
Engine Overheating 0326.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer
on a level surface when possible.
When parking your vehicle and your
trailer on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the
wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake
pedal to allow the chocks to absorb
the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.

Engine Oil
To ensure proper engine performance
and long life, careful attention must
be paid to engine oil. Following these
simple, but important steps will help
protect your investment:
.Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil” in
this section.
.Check the engine oil level regularly
and maintain the proper oil level.
See “Checking Engine Oil” and
“When to Add Engine Oil” in this
section.
.Change the engine oil at the
appropriate time. See Engine Oil Life
System 0318.
.Always dispose of engine oil
properly. See “What to Do with Used
Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick
handle is a loop. See Engine
Compartment Overview 0313 for the
location.
{Warning
The engine oil dipstick handle may
be hot; it could burn you. Use a
towel or glove to touch the dipstick
handle.
If a low oil Driver Information Center
(DIC) message displays, check the oil
level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the
engine oil level after the engine has
been off for at least two hours.
Checking the engine oil level on
steep grades or too soon after
engine shutoff can result in incorrect readings. Accuracy
improves when checking a cold
engine prior to starting. Remove the
dipstick and check the level.
.If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is warm,
or at least 30 minutes if the engine
is not warm. Pull out the dipstick,
wipe it with a clean paper towel or
cloth, then push it back in all the
way. Remove it again, keeping the
tip down, and check the level.
